SAW SET.

Application filed May 16,

To all whom it may concern:

Be it known that I, HENRY LnsLIn CAR- MAN, a citizen of the UnitedStates of America, residing at Flagstaff, in the county of Coconino andState of Arizona, have invented new and useful Improvements in Saw Sets,of which the following is a specification.

The object of the invention is to provide a simple and convenient formof portable manually operable saw-set adapted to be operated withoutincurring any severe effort on the part of the operator andunderconditions insuring a relative accuracy in the setting of the teeth inso far as uniformity is concerned and under conditions providing for avariation in the position of the tool to suit the convenience of theoperator and the peculiarities of the saw which is being dressed; andwith these objects in view the invention consists in a'construction andcombination ofparts of which a preferred embodiment is shown in theaccompanying drawings, wherein:

Figure 1 is a perspective View of a sawset embodying the inventionapplied in the operative position to a saw in the operation of setting atooth and indicating in relation thereto the positionof the hammer usedin that connection;

Fig. 2 is a side View of the same showing thetoolin another positionwith relation to the saw blade under conditions requiring the hammerstroke to be applied to the tooth itself and for giving the tooth a setin the opposite direction from that indicated in Fig. 1, as when it isdesired to operate th tool uniformly from one side of the saw bladeinstead of reversing the same in dressing the teeth in oppositedirections;

Fig. 3 is a view showing the tool in still another setting position; and

Fig. 4 is a view in an additional setting position in which the extentof deflection of the tooth must be determined by the eye of the operatorwithout the aid of a guide.

The tool consists essentially of a shank or handle 10 which ispreferably of tapered form as shown to afford a firm grip by theoperator and resist a tendency to move the grip longitudinally in thehand of the operator when the blow 'of the setting hammer is applied tothe end of the head 11 which is'of arched or gooseneck form representedin the draw a a n inuat on of the 1922. Serial No. 561,436.

shank or handle and having a depending aw 12 between the inner side ofwhich and the adjacent face 13 of the head which constitutes an opposingjaw there is provided a tapered throat 1 1 in communication with an eye15 designed for the reception of a saw tooth '16. At its apex the throatmerges into a narrow passage 17 of a width just sufficient to receivethe thickness of the saw blade and disposed at an inclination to theinner face of the jaw 12, so that if the tool is placed on the saw bladewith the inner face of the aw 12 in contact or parallelism with theblade, and the blow of a hammer is applied to an impact face 18 at thecrown of the arch formed by the head the tooth which is opposite theseat formed by the passage 17 will be set at exactly the. proper anglewithout further effort or manipulation on the part of the operator.

Should it be desired to effect the setting of a tooth without fittingthe throat over the sa-wblade as for example in the event that thesetting operation is being performed on a blade of greater thicknessthan is provided for bythe throat, the outer face of the jaw 12 may beapplied to the surface of the saw blade and the bevel 19 at the springof the arch formed by the head may be utilized as the setting seat,butin this method of using the tool it is necessary to apply the blow ofthe hammer to the tooth so as to drive the tooth laterally into contactwith the seat 19.

In the same way a tooth may be set as shown in Fig. 3 by turning thetool at right angles to the position indicated in Figs. 1 and 2 or withthe jaw 12 parallel with the saw blade and with the outer surfacethereof in contact with the surface of the blade, whereupon the beveledsetting seat 20 may be utilized under conditions similar to thosedescribed in reference to the seat 19, in that the tooth to be set mustbe struck directly by the hammer.

Again should it be desired to set a tooth at a slightly greater anglethan provided for by the seats hereinabove described, or should it bedesired to set a tooth with a more abrupt angle at the line ofdeflection from the plane of the blade proper, the tool may be reversedfrom the position indicated in Fig. 3 as shown in Fig. 4 to utilize theangle 21 which is placed at the base of the tooth to be set, In this useof the device,

however, the operator must depend upon his eraiiy' "required *b ut eyeto determine how far to deflect the 19 is the one which in" practicewill be most generally used in the setting of saw teeth for the reasonthatit pre my. 1 )l the tool readily to the tents. and close theoperation of bringing the tooth by the blows of the hammer into properrelation with the seat and further by reason of the fact that a seatl inown is mos a hort berei by the seat 20 is of utility under speciaiconditions and can be utilizedpractically with the same facility as theseat l9 while the abrupt or right angle setting are represented by theangle 21 will probably in practice be necessary only occasionally as ameans of setting a tooth as for example when a particularly long bevel.is required and the angle may be arranged at a short distance below theline of the tooth base.

The special purpose of the seat 17 is to remove from the tooth thesl'ionlder which frequently forms thereon after a saw has been run for aconsiderable timeand which appears just below the top of the crank ofthe tooth and has the efiectof making the saw run integrally. Thisshoulder be entirely removed by applying the tool thereto in the mannerfirst above described that is through the tapered throat 14 so to bringthe tooth into engagement with the seat 17 and tapping the impact face18 generally with the hammer in the direction of the: arrow adjacentthereto.

A special advantage of the tool in addition to the tapering of thehandle or grip resides in the fact that it is compact and handle shankwhich niei an 'arciiahely urred" net in pertiorn" the said" that thehand of the operator in grasping soft portion of the hand whereby it iscushioned to resist hlows'applied to the outer face of the jaw 12 by ahammer operating in Having described the invention what is claimed asnew andfuseful is s A saw-set comprising: body having a s. at one,end'rinto neck portion merging into a head portion hELVlHQ' parallelopposite side surfaces disposed at right angles to the length of thehandle shank, the neck portion being-provided at its outer side'with aplane striking surface disposed parallel with the longitudinal dimensionofthe'handle shank and at a right angle to thepfl'anes'of the parallelside surfaces of the head portion, said striking surface being disposedbetween the planes of the parallel side surfaces oi the head portion,the inner. surface of the neck portion forming" an eye-which is disposedbetween the parallel side surfaces of the head portion and at one sideof the median longitudinal dimension of the handle shank, the headportion being spaced from the handle shank by a. threat whichcommunicates with the eye, and the opposite side surfaces of which aredisposed at a'cuteangles to the parallel side surfaces ofthe headportion, the striking surface, and the median longitudinal: dimension ofthe handle shank.

In testimony whereof he affixes his signature. 5
